我正在尝试将SQL Select-Query的结果转换为DataTables可读格式的JSON文件。
现在我将结果转换为这种形式：
{
"data":[
[
"pIdWrittenHere1232131231",
"sNameWrittenHere",
"lNameWrittenHere",
"http://Some.pLogUrl.writtenHere.com/",
"incentivWrittenHere",
"https://someDetailsUrl.WrittenHere.com/
],
[
"pId2WrittenHere1232131231",
"sName2WrittenHere",
"lName2WrittenHere",
"http://Some.pLogUrl.writtenHere.com/",
"incentiv2WrittenHere",
"https://someDetailsUrl.WrittenHere.com/
]
]
}
这是我用来实际转换它们的php：

我必须在php中更改某些内容，以便在数据表中获取数据...
这是我的JavaScript：
$(document).ready(function() {
$('#oShopTable').DataTable( {
"bProcessing": true,
"bServerSide": true,
"ajax": "AdminPage2.php"
} );
} );
当我使用此echo json_encode($output, JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);
var_dump($output['data'][0]);时，返回此处
array(6) {
[0]=> string(8) "pIdHere12312312"
[1]=> string(10) "sNameHere"
[2]=> string(17) "lNameHere"
[3]=> string(85) "https://somePLogUrlHere.com"
[4]=> string(22) "incentivHere"
[5]=> string(161) "someUrlHere"
}
答案 0 :(得分：0)
尝试类似的东西：
$query = "SELECT `id` AS `pId` FROM `table`";
// ...
$data = array('data' => mysql_fetch_assoc ($rResultFilterTotal));
$jsonData = json_encode($data);

答案 1 :(得分：-1)
所以..这是解决方案！
这里是我想要显示DataTable的页面的HTML代码（index.php）：
<div class="panel-body">
<table id="oShopP" class="display">
<thead>
<tr>
<th>Price Id</th>
<th>Sync Name</th>
<th>Light Name</th>
<th>Price Logo Url</th>
<th>Incentiv</th>
<th>JTS URL</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Price Id</th>
<th>Sync Name</th>
<th>Light Name</th>
<th>Price Logo Url</th>
<th>Incentiv</th>
<th>JTS URL</th>
</tr>
</tfoot>
</table>
</div>
这里是AdPage-data.php的php：
<?php
/* Database connection start */
$servername = "localhost";
$username = "usernameHere";
$password = "passwordHere";
$dbname = "dbNameHere";
$conn = mysqli_connect($servername, $username, $password, $dbname) or die("Connection failed: " . mysqli_connect_error());
/* Database connection end */
// storing request (ie, get/post) global array to a variable
$requestData= $_REQUEST;
$columns = array(
// datatable column index => database column name
0=> 'p_Id',
1=> 's_Name',
2=> 'l_Name',
3=> 'pLogo_Url',
4=> 'incentivation',
5=> 'det_jtsURL'
);
// getting total number records without any search
$sql = "SELECT p_Id, s_Name, l_Name, pLogo_Url, incentivation, det_jtsURL";
$sql.= " FROM tableNameHere";
$query=mysqli_query($conn, $sql);
$totalData = mysqli_num_rows($query);
$totalFiltered = $totalData; // when there is no search parameter then total number rows = total number filtered rows.
$sql = "SELECT p_Id, s_Name, l_Name, pLogo_Url, incentivation, det_jtsURL";

}
$query=mysqli_query($conn, $sql);
$totalFiltered = mysqli_num_rows($query); // when there is a search parameter then we have to modify total number filtered rows as per search result.
$sql.=" ORDER BY ". $columns[$requestData['order'][0]['column']]." ".$requestData['order'][0]['dir']." LIMIT ".$requestData['start']." ,".$requestData['length']." ";
/* $requestData['order'][0]['column'] contains colmun index, $requestData['order'][0]['dir'] contains order such as asc/desc */

$nestedData=array();
$nestedData[] = $row["p_Id"];
$nestedData[] = $row["s_Name"];
$nestedData[] = $row["l_Name"];
$nestedData[] = $row["pLogo_URL"];
$nestedData[] = $row["incentivation"];
$nestedData[] = $row["det_jtsURL"];
$data[] = $nestedData;
}
$json_data = array(
"draw" => intval( $requestData['draw'] ), // for every request/draw by clientside , they send a number as a parameter, when they recieve a response/data they first check the draw number, so we are sending same number in draw.
"recordsTotal" => intval( $totalData ), // total number of records
"recordsFiltered" => intval( $totalFiltered ), // total number of records after searching, if there is no searching then totalFiltered = totalData
"data" => $data // total data array
);
echo json_encode($json_data); // send data as json format
?>
这里是jquery：
$(document).ready(function() {
var dataTable = $('#oShopP').DataTable( {
"processing": true,
"serverSide": true,
"ajax":{
url :"AdPage-data.php", // json datasource
type: "post"
}
});
} );
当然index.php和AdPage-data.php必须位于同一个文件夹中，因此这段代码正好可以使用。
